The preparation steps of the four-silver low-radiation energy-saving window film are described in detail as follows:
(1) firstly, a flexible transparent PET film is provided as the flexible transparent PET substrate layer 1. In one embodiment, in order to obtain better light transmittance, the visible light transmittance of the flexible transparent PET substrate layer 1 is more than or equal to 89%, and the haze is less than or equal to 1.5.
(2) Depositing a first high-refractive-index layer 2 on the PET substrate layer 1 by a double-rotating cathode and medium-frequency reactive magnetron sputtering method, wherein the refractive index of the first high-refractive-index layer 2 is preferably 2.36. The first high-refractive-index layer 2 is directly deposited on the PET film in a magnetron sputtering mode, and Nb is adopted2O5Has good adhesive force with PET film, adopts Nb2O5The coating can be directly deposited on a PET film, and the PET film does not need to be subjected to additional metal coating treatment to improve the adhesive force, so that the number of layers can be reduced, the light transmittance can be improved, and meanwhile, if the metal coating treatment is adopted, the color of the window film can be damaged, and the expected turquoise color cannot be obtained.
(3) And depositing a first metal oxide layer 3 on the first high-refractive-index layer 2 by a single-rotating cathode and direct-current reactive magnetron sputtering mode. The grass green window film of the present invention employs three layers of ZnO: Al layer (aluminum doped zinc oxide layer) and one layer of ZnO: Sn layer (tin doped zinc oxide layer), see steps 7, 11 and 15. The thickness of the four doped zinc oxide layers is very small and is only a few nanometers, but the doped zinc oxide layers with the thickness of a few nanometers can promote the growth of the subsequent silver alloy layer to enable the subsequent silver alloy layer to grow into a continuous compact structure as soon as possible, so that the thickness of the subsequent silver alloy layer is obviously reduced, and the light transmittance of the window film is improved. Meanwhile, the compact silver alloy layer can effectively reflect infrared rays and ultraviolet rays, and the heat insulation performance of the window film is improved. In a preferred embodiment, the thickness of each doped zinc oxide layer is less than or equal to 2/3 the thickness of the subsequent silver alloy layer, i.e. the preferred light transmission and thermal insulation properties are achieved. That is, the thickness of the first metal oxide layer 3 is equal to or less than 2/3 of the thickness of the first silver alloy layer 4; 2/3 where the thickness of the second metal oxide layer 7 is equal to or less than the thickness of the second silver alloy layer 8; 2/3 where the thickness of the third metal oxide layer 11 is equal to or less than the thickness of the third silver alloy layer 12; the thickness of the fourth metal oxide layer 15 is equal to or less than 2/3 the thickness of the fourth silver alloy layer 16.
(4) A first silver alloy layer 4 is deposited on the first metal oxide layer 3 by means of a single-plane cathode and direct-current reactive magnetron sputtering. Preferably, the silver alloy layer comprises 96% of Ag and the balance of 4% of Cu, which can achieve better oxidation resistance and moisture resistance compared with pure silver, and of course, the silver alloy layer is mainly configured to reflect infrared rays and ultraviolet rays to provide excellent heat insulation performance. Meanwhile, it should be noted that, since the thickness of the silver alloy layer is greater than or equal to 3/2 times of the thickness of the doped zinc oxide layer thereunder, and the density of the formed silver alloy layer is high, the color of the window film of the present invention is greatly influenced by the thickness of the silver alloy layer, and of course, for the arrangement of the four silver alloy layers of the present invention, the spacing between the four silver alloy layers and the refractive index matching relationship of the five high refractive layers are also indispensable factors for obtaining the color of the grass green window film, which will be described in detail later.
In a preferred embodiment, in step four, the first silver alloy layer 4 may be deposited on the first metal oxide layer 3 by disposing a UV mask in parallel horizontal arrangement, and then removing the UV mask to form the first silver alloy layer 4 in parallel horizontal direction stripe shape. For example, the UV mask may be formed by spraying a layer of UV paste on the first metal oxide layer 3, irradiating the UV paste with UV light from behind the horizontally arranged stripe grating to cure the irradiated portion of the UV paste, and removing the uncured UV paste to form the horizontally parallel arranged UV mask.
The striped first silver alloy layers 4 arranged in parallel in the horizontal direction may form different transmittances and reflectances in the longitudinal direction, but do not affect the sight line in the parallel direction, so that when a user looks outward from the inside of the window glass close to the window glass, the sight line of the user is almost horizontally perpendicular to the striped direction, and thus does not affect the outward sight line. When people outside the window glass observe, the distance is usually long, so that the people are easily influenced by different light transmittance and reflectivity in the longitudinal direction, the sight is blurred, the image is mottled, and peeping can be prevented.
(5) And depositing a first barrier layer 5 on the first silver alloy layer 4 by a single-plane cathode and direct-current reactive magnetron sputtering mode. The first barrier layer 5 is used for protecting the first silver alloy layer 4, so that the first silver alloy layer 4 is prevented from being oxidized to reduce the light transmission and reflection performance, the infrared light reflectivity of the silver alloy layer is ensured not to be reduced along with the prolonging of the service time, the service life of the window film is prolonged, and the window film has a lasting high heat insulation effect. In a preferred embodiment, the thickness of the first barrier layer 5 is less than or equal to 1/5 of the thickness of the first silver alloy layer 4 thereunder, and the thickness ratio can obtain the required oxidation resistance by using the first barrier layer 5 with the minimum thickness, so that the optimal heat insulation effect can be obtained by using the minimum thickness, and the whole light transmission performance of the window film is improved.
(6) And depositing a second high-refractive-index layer 6 on the first barrier layer 5 by a double-rotating cathode and medium-frequency reactive magnetron sputtering method, wherein the refractive index of the second high-refractive-index layer 6 is preferably 2.36. The thickness of the second high refractive index layer 6 in this step is larger than that of the innermost and outermost high refractive index layers, that is, for the four silver alloy layers of the present invention, the second high refractive index layer 6, the third high refractive index layer 10 and the fourth high refractive index layer 14 having a large refractive index are disposed between the four silver alloy layers, and a double reflection structure for reflecting infrared rays and ultraviolet rays can be formed with a smaller interval between the two silver alloy layers, so that the thicknesses of the second high refractive index layer 6, the third high refractive index layer 10 and the fourth high refractive index layer 14 can be reduced, and the overall light transmission performance of the window film can be improved.
(7) A second metal oxide layer 7 is deposited on the second high refractive index layer 6 by means of single rotating cathode, dc reactive magnetron sputtering. The thickness of the second metal oxide layer 7 deposited in this step is slightly greater than that of the first metal oxide layer 3 in the previous step 3, so that more infrared and ultraviolet rays are reflected by the thicker second silver alloy layer 8 of the outer layer, and the second silver alloy layer 8 of the outer layer is reduced, so that the first silver alloy layer 4 of the inner layer can be thinner, and the thickness of the corresponding first metal oxide layer 3 can be reduced. The optical uniformity of the window film can be improved by matching the thicknesses of the first metal oxide layer 3, the second metal oxide layer 7, the third metal oxide layer 11 and the fourth metal oxide layer 15, but the most significant effect is that the chromaticity of the window film of the present invention can be adjusted, i.e., the turquoise color of the turquoise window film of the present invention is mainly determined by the thickness proportional relationship of the first metal oxide layer 3, the second metal oxide layer 7, the third metal oxide layer 11 and the fourth metal oxide layer 15 and the first silver alloy layer 4, the second silver alloy layer 8, the third silver alloy layer 12 and the fourth silver alloy layer 16 thereon. This is the optimal combination of parameters that distinguishes the present invention from other technologies, and there is no solution in the prior art that provides a principle of combination of parameters for obtaining a grass green window film, which is unobvious, with outstanding substantive features and significant advances.
(8) A second silver alloy layer 8 is deposited on the second metal oxide layer 7 by means of a single-plane cathode, direct current reactive magnetron sputtering. Preferably, the silver alloy layer comprises 98% of Ag and the balance of 2% of Pd. The second silver alloy layer 8 forms an intermediate reflection structure for reflecting infrared rays and ultraviolet rays, so that the thickness of the window film is reduced, the light transmittance is improved, and the heat insulation performance is enhanced.
Similarly, as in step four, in a preferred embodiment, during the magnetron sputtering in step eight, a second silver alloy layer 8 may be deposited on the second metal oxide layer 7 by disposing a horizontally parallel UV mask, and then removing the UV mask to form a second silver alloy layer 8 in the form of stripes horizontally parallel to each other. The manner of forming the UV mask is as described above and is not repeated.
However, the stripes of the second silver alloy layer 8 formed in this step, which are arranged in parallel in the horizontal direction, and the stripes of the first silver alloy layer 4, which are arranged in parallel in the horizontal direction, are preferably arranged to be offset from each other, that is, the stripes of the second silver alloy layer 8 face the gaps of the stripes of the first silver alloy layer 4, and the gaps of the stripes of the second silver alloy layer 8 face the stripes of the first silver alloy layer 4. In another preferred embodiment, the width of the stripe can be set to be the same as the width of the gap, so that the setting of the stripe mask is facilitated, and the two layers of stripes are arranged in a staggered manner, so that the process is simplified and the processing is facilitated.
The stripes arranged in a staggered mode shield the respective gaps, and the reduction of heat insulation and reflection effects due to the existence of the gaps can be avoided. Meanwhile, the stripes are arranged in a staggered mode, so that when the glass is observed close to the window glass (within 1 meter), the light transmittance and the reflectivity are almost the same, namely, the existence of the stripes can not be detected from outside to inside and from inside to outside, and when the glass is observed from outside 1 meter, the peeping prevention effect can be generated due to the existence of the sight line included angle. Meanwhile, the striped silver alloy layer reduces the shielding range, improves the light transmittance, and has relatively small influence on the function and the color uniformity of the window film.
(9) The second barrier layer 9 is deposited on the second silver alloy layer 8 by a single-plane cathode and direct-current reactive magnetron sputtering mode, so that the second silver alloy layer 8 is protected and prevented from being oxidized, the reflectivity of infrared light of the silver alloy layer is ensured not to be reduced along with the prolonging of the service time, the service life of the window film is prolonged, and the window film has a lasting high heat insulation effect. In a preferred embodiment, the thickness of the second barrier layer 9 is less than or equal to 1/5 of the thickness of the second silver alloy layer 8 below the second barrier layer, and the thickness ratio can obtain the required oxidation resistance by using the second barrier layer 9 with the minimum thickness, so that the optimal heat insulation effect can be obtained by using the minimum thickness, and the overall light transmission performance of the window film is improved.
(10) Depositing a third high refractive index layer 10 on the second barrier layer 9 by means of double-rotating cathode and medium-frequency reactive magnetron sputtering, wherein the refractive index of the third high refractive index layer 10 is preferably 2.36. The third high refractive index layer 10 close to the outer side in the middle is selected to effectively reflect infrared light and ultraviolet light in sunlight, and the heat insulation performance of the window film is further improved.
(11) And depositing a third metal oxide layer 11 on the third high-refractive-index layer 10 by a single-rotating cathode and direct-current reactive magnetron sputtering mode. The function and function of the third metal oxide layer 11 has already been mentioned in the description of the first metal oxide layer 3.
(12) A third silver alloy layer 12 is deposited on the third metal oxide layer 11 by means of a single-plane cathode, dc reactive magnetron sputtering. The function and function of the third silver alloy layer 12 has already been mentioned in the introduction of the first silver alloy layer 4. Preferably, the silver alloy layer comprises 96% of Ag and the balance of 4% of Cu, so that better oxidation resistance and moisture resistance can be obtained compared with pure silver, and infrared rays and ultraviolet rays can be reflected to provide excellent heat insulation performance.
Similarly, as in the fourth step and the eighth step, in a preferred embodiment, in the magnetron sputtering process of the twelfth step, a third silver alloy layer 12 may be deposited on the third metal oxide layer 11 by disposing a UV mask arranged in parallel horizontally, and then removing the UV mask to form a third silver alloy layer 12 in a stripe shape arranged in parallel horizontally. The manner of forming the UV mask is as described above and is not repeated.
Similar to step eight, the stripes of the third silver alloy layer 12 formed in this step, which are arranged in parallel with the horizontal direction, and the stripes of the second silver alloy layer 8, which are arranged in parallel with the horizontal direction, are preferably arranged offset from each other, i.e., the stripes of the third silver alloy layer 12 face the gaps of the stripes of the second silver alloy layer 8, and the gaps of the stripes of the third silver alloy layer 12 face the stripes of the second silver alloy layer 8.
The stripes arranged in a staggered mode shield the respective gaps, and the reduction of heat insulation and reflection effects due to the existence of the gaps can be avoided. Meanwhile, the stripes are arranged in a staggered mode, so that when the glass is observed close to the window glass (within 1 meter), the light transmittance and the reflectivity are almost the same, namely, the existence of the stripes can not be detected from outside to inside and from inside to outside, and when the glass is observed from outside 1 meter, the peeping prevention effect can be generated due to the existence of the sight line included angle. Meanwhile, the striped silver alloy layer reduces the shielding range, improves the light transmittance, and has relatively small influence on the function and the color uniformity of the window film.
(13) And depositing a third barrier layer 13 on the third silver alloy layer 12 by a single-plane cathode and direct-current reactive magnetron sputtering method. The third barrier layer 13 has a similar structure function to the second barrier layer 9, and similarly, in a preferred embodiment, the thickness of the third barrier layer 13 is less than or equal to 1/5 of the thickness of the third silver alloy layer 12 therebelow, and the thickness ratio can obtain the required oxidation resistance by using the third barrier layer 13 with the minimum thickness, so that the optimal heat insulation effect can be obtained by using the minimum thickness, and the overall light transmittance of the window film is improved.
(14) And depositing a fourth high-refractive-index layer 14 on the third barrier layer 13 by means of double-rotating cathode and medium-frequency reactive magnetron sputtering, wherein the refractive index of the fourth high-refractive-index layer 14 is preferably 2.36. Also as the fourth high refractive index layer 14 in the middle, near the outer side, is selected to effectively reflect infrared and ultraviolet light in sunlight, further improving the thermal insulation properties of the window film.
(15) A fourth metal oxide layer 15 is deposited on the fourth high refractive index layer 14 by means of single rotating cathode, dc reactive magnetron sputtering. The function and function of the fourth metal oxide layer 15 has already been mentioned in the description of the first metal oxide layer 3.
(16) A fourth silver alloy layer 16 is deposited on the fourth metal oxide layer 15 by means of a single-plane cathode, dc reactive magnetron sputtering. The function and function of the fourth silver alloy layer 16 has already been mentioned in the introduction of the first silver alloy layer 4. Preferably, the silver alloy layer comprises 96% of Ag and the balance of 4% of Cu, so that better oxidation resistance and moisture resistance can be obtained compared with pure silver, and infrared rays and ultraviolet rays can be effectively reflected to provide excellent heat insulation performance.
Similarly, as in the fourth step, the eighth step and the twelfth step, in a preferred embodiment, in the magnetron sputtering process of the sixteenth step, the fourth silver alloy layer 16 may be deposited on the fourth metal oxide layer 15 by disposing a UV mask horizontally arranged in parallel, and then removing the UV mask to form the fourth silver alloy layer 16 in a stripe shape horizontally arranged in parallel. The manner of forming the UV mask is as described above and is not repeated.
Similarly to the twelfth step, the stripes of the fourth silver alloy layer 16 formed in the present step, which are arranged in parallel with the horizontal direction, and the stripes of the third silver alloy layer 12, which are arranged in parallel with the horizontal direction, are preferably arranged to be offset from each other, that is, the stripes of the fourth silver alloy layer 16 face the gaps of the stripes of the third silver alloy layer 12, and the gaps of the stripes of the fourth silver alloy layer 16 face the stripes of the third silver alloy layer 12.
In another preferred embodiment, the first silver alloy layer 4, the second silver alloy layer 8, the third silver alloy layer 12 and the fourth silver alloy layer 16 may be provided with a stripe width equal to 1/3 of the gap width between the stripes, which facilitates the provision of a stripe mask, and also facilitates the arrangement of four stripes in a staggered manner, which simplifies the process and facilitates the processing. That is, the gaps between adjacent stripes on the first silver alloy layer 4, the second silver alloy layer 8, the third silver alloy layer 12 and the fourth silver alloy layer 16 are 3 times of the stripe width, and the stripes of the four silver alloy layers are staggered by one stripe width, so that the four stripes can just shield the gap position.
The stripes arranged in a staggered mode shield the respective gaps, and the reduction of heat insulation and reflection effects due to the existence of the gaps can be avoided. Meanwhile, the stripes are arranged in a staggered mode, so that when the glass is observed close to the window glass (within 1 meter), the light transmittance and the reflectivity are almost the same, namely, the existence of the stripes can not be detected from outside to inside and from inside to outside, and when the glass is observed from outside 1 meter, the peeping prevention effect can be generated due to the existence of the sight line included angle. Meanwhile, the striped silver alloy layer reduces the shielding range, improves the light transmittance, and has relatively small influence on the function and the color uniformity of the window film.
